I'm trying to write a small app, in Python, to set the background on seperate monitors to different wallpapers. My app right now will span, tile or center the wallpaper over the two monitors in a Twinview setup. I know that I need to access the Display Device Name such as CRT-0 or DFP-0 to get different background on each monitor but I'm unsure how to access them. Any pointer would be great.
